The 3D graphic display represents a rotor and a stator of an induction motor. Also shown is a plot of the three\[Hyphen]phase supply. The rotor illustrates the rotor bars and other major parts of a typical induction motor rotor. The stator shows six phase bands representing each of the winding sides of a typical two-pole machine. The phase bands illuminate when the phase polarity is positive. This provides a visualization of the rotating nature of the created magnetic field. The rotor speed is controlled by the magnitude of the magnetic field. If you adjust the controls such that the magnetic field magnitude is not consistent, the rotor will slow down and speed up in relation to the field. This illustrates the change in torque that results in an induction motor under similar circumstances. This effect is exaggerated to allow this phenomenon to be observed.
